Confidence is key to success in any sport and Fermanagh manager Pete McGrath believes his side have the work done that will see them perform to their best against Dublin in Sunday's All-Ireland SFC quarter-final.
Speaking ahead of the game to RTÉ Sport, McGrath said: "We think we are pretty sound defensively. Our scores for have been pretty good and hopefully we can bring the best aspects of our play into the game on Sunday and perform as well as we possibly can.
"I'm confident if we can do that we'll be asking a lot of questions of Dublin."
Fermanagh forward Tomás Corrigan is also hopeful their system of play will serve them well at Croke Park.
"We've been working on the system that Pete has put in place since last November with the aim of implementing it in the championship. We'll have to play to the best of our ability and perfect that system on Sunday."
